this is something mathcad had done very well imo. it provided you with a blank page where you could write anywhere and the equations nearly looked like they had been written with latex. even better, all changes to variables were live and you could tweak things anywhere to see how it effected your numbers. miss it a lot. calca is similar to it now on the mac, but not nearly as pretty and you still end up with lines of text and no equations.
